Overview

Practical learning for workplace transfer.

Interpret crude assays, predict blend behavior and connect feed quality to unit constraints, yields, product value and purchasing decisions. Participants work through five connected modules using discipline-specific evidence, calculations and an applied decision case.

Prerequisites

Prior exposure to process operations, PFDs and engineering calculations is recommended.

Objectives

  • Interpret crude characterization and assay quality using traceable evidence and an explicit decision criterion.
  • Calculate distillation curves and property estimation using traceable evidence and an explicit decision criterion.
  • Diagnose blend compatibility and stability risks using traceable evidence and an explicit decision criterion.
  • Evaluate unit constraints, yields and refinery value using traceable evidence and an explicit decision criterion.
  • Deliver crude slate evaluation workshop using traceable evidence and an explicit decision criterion.

Target audience

  • Process, operations and process-safety engineers
  • Control, inspection and technical-assurance specialists
  • Technical assurance, data and reliability practitioners
  • Supervisors and discipline leads responsible for operational decisions
